Side note to all, I don't mind a bit of thread derivation as long as semi close to topic or in fun but if yall want to have a pissing contest start your own thread.
Good deal, glad for you and disregard the noise on this thread about anything else.
Post a video of the first run and speaking from experience DO NOT bri g the family it is bad luck. Do alone or with a buddy that can fix stuff. Then the family.
I'd push the pin on the handle gear then turn handle and see if clear then do the next to find which one is tougher. My guess is is needing lube in the vertical shaft but unsure how.
Cabinet screws all the way. Besides the washer head the threads are different than a regular screw. Do some googling to find what you need for what you are doing.

I know this setup is way diff than mine but I could not identify leak location(s) by filling up the boat. The sand silt and muck plugged the holes. Until I ripped the floor up and cleaned out no water dripped. Do it anyway just thought id chime in on my experience.
